Hi Zhen,
Thank you for contacting the Mobile Ads SDK Support team.
Error code 1: ERROR_CODE_INVALID_REQUEST, The ad request was invalid; for instance, the ad unit ID was incorrect.
This commonly suggests that the Ad Request implementation is not as per the SDK’s requirements - Resources like the sample codes and sample apps provided in the developer documentation can help in implementing the functions correctly. You can check our Google Sample Project for reference.
Would you be so kind as to verify the accuracy of your ad unit ID and make the necessary correction in the sample project.
If the issue still persists, kindly provide the below information via the reply to author option, so that we will review your account and let you know why ads aren’t showing.
